I had John build a retaining wall on the north side of the house where the lot slopes down a bit. The north side of the house is the kid bedrooms and the only window is a transom above the tub/shower. I wanted the heat pump to sit up higher, so I put John and the tractor to work. After about 5 hours I came out to check progress and we realized that I had failed to communicate what I wanted. That was a days work lost for John, poor guy! After several weekends, he finished! It looks great! We plan to plant strawberries there this spring.
